The GReddy R35 GT-R DCT Transmission Cooler Kit — the proven answer to DCT heat soak. A large 13-row inner-fin core mounted in the front fender, fed by a model-year-specific FRP divided air duct that mirrors the OEM unit on the other side of the car.
This is a parallel system with a billet internal thermostat adapter, so the transmission warms up quickly and holds consistent oil temps without taxing the coolant system. Lightweight 14mm hard lines and braided lines keep routing short and flow high.
Kit includes:
- Machined aluminum oil block for R35 GTR with built-in thermostat
- GReddy blue NS1310G oil cooler core (12004314)
- Aluminum hard lines, black nylon mesh hose, and GReddy fittings
- FRP duct with special inner blade
- Mounts, hose fittings, and 3-piece billet flanges with O-rings
Note: a separate washer tank is required if you want to keep your windshield washer system after install. Select your generation above.
